Border security to prevent unauthorized migration along the U.S-Mexico border is a dynamic and challenging problem that has not consistently been mitigated by allocating increased resources, such as fencing and surveillance, says a newly updated report from the Congressional Research Service.
“Robust investments at the border were not associated with reduced unauthorized inflows during the 1980s and 1990s, but a range of evidence suggests a substantial drop in unauthorized inflows from 2007 to 2011, followed by a rise from 2012 to 2014 and a decrease in 2015,” CRS said.
